Private magnetic-confinement fusion ventures have achieved steady-state plasma stability durations previously limited to national laboratory facilities. High-temperature superconducting magnets are enabling higher magnetic field densities within smaller reactor footprints.
Materials Engineering Next Bottleneck
While plasma confinement stability has advanced, reactor wall erosion and neutron degradation remain key engineering obstacles. Researchers are prioritizing liquid lithium blankets and advanced tungsten alloys to withstand continuous heat fluxes in prospective power plants.
